Hello,
I am using DRV8305N in my Motor Control Application.
So far I was using Low-Side Current sensing and integrated CSA's in DRV8305N.
Now I redesigned a little my project to have external CSA (INA241) and In-Phase Shunt resistors
It was only this change, current sensed by INA seen at ADC is corrected (checked it), but DRV is giving errors/damaging.
This is stragne because nothing apart way of current sensing changed and current sensing itself is workign correctly looking at the ADC valuse.
I have SNx/SPx Inputs left floating and all SL_x (so source of low-side) are now (in case of lack of low-side shunts) tied to GND like in the picture:
Can DRV work in that configuration? I am debugging the problem but maybe some has some suggestion what could be the problem?
Regards,
Adam
